Z Fold 4 Crashes when Unfolding

[jhk987]

So recently MY ZF4 has started giving me a black screen and become unresponsive when I unfold the phone, it will also then sometimes automatically restart itself after the screen goes black. I have tried everything, including a factory reset but nothing has fixed this. I am just wondering it anybody else has had this? This phone is not even a month old, if it is a bug in the hardware or software, samsung needs to address it,

I have started having the same issue for two days now, can only use the phone with the cover screen for now. Going to take it to service to have it looked at, seems like a hardware issue

Same issue here, started today without warning crashes every time I open it.. also no sound from built in speakers on playback but sound on Bluetooth. Less than six months old and never dropped or near water.

*****, may it be a coincidence or not: I received the OneUI5.1 Update a few days ago, and this issue started immediately afterwards: Not every time, but >50% of all the times I "unfold" my Fold4, the speakers make a buzzing sound, and the screen gets dark. Only fix is a soft-reset with holding all the buttons down...
Is this for sure a hardware problem? If yes this sucks big way!!! 😞

FIXED MINE! I had a suspicion that the switch was not triggering on and or causing the phone to turn off when unfolding. I put the phone under hot running water and completely washed it and continously opened and closed it submerged in water.  Suddenly it lit up! It works now!
